WATER-CLOSET BOWL AND TRAP SPECIFICATION forming part of Letters Patent No. 423,022, dated March 11, 1890. Application filed January 12, 1889. Serial No. 296,185. (No model.)

To all whom it may concern:

Be it known that I, JAMES E. BOYLE, a citizen of the United States, residing at Brooklating-pipe leading from the space between. the water seal and the outlet to the soil-pipe:

for the purpose of conducting away any foul gases. that may arise from the sewer, and for the formation of a vacuum in the soil or sewer pipe by affording the latter a free com that atmospheric pressure is maintained adjacent to the trap.

tion between the pipe and such an opening,

7 and for the further reason that the opening,

being usually at'the front, the connection projects forward beyond the earthenware bowl, being unsightly and in the way. A tubular barrel of earthenware has also been molded upon the exterior of thetrap and communicating by an opening with the portion thereof between the water seal and the outlet, a through-and-through connection being applied to this barrel, the tie-rod or portion thereof passing through the barrel and drawing the two packed heads of the connection together against the ends of the barrel.

Such a connection has the advantage that the metal parts by which the pipe is joined are reversible and are easily applied, but it is disadvantageous because of the projection of the earthenware barrel beyond the general outline of the water-closet trap,whereby it is more or less in the way and is liable tobecome injured.

My present invention provides a back-air connection for earthenware closet-traps,.which involves no projection whatever from the general outline of the trap portion of the closet, and which has the further advantage that the connection is applied toward the rear of the closet, thereby carrying it as far as possible out of sight and strengthening the connecting-pipe, whereby the entire structure when set is rendered more sightly and workmanlike.

In the accompanying drawings I have shown my invention as applied to several different kinds or styles of water-closets.

Figure 1 is a side elevation of a doubletrapped pneumatic water-closet of what is known in the trade as the Tidal-Wave Class, the particular closet here shown being known as the Crystal. Fig. 2 is a vertical mid-section thereof, looking in the same direction as Fig.1. Fig. 3 is afront elevation thereof. Fig. 4 is a horizontal section cut in the plane of the line 4 4 in Fig. 2. Fig. 5 is a sectional elevation, on a larger scale, of the metallic through-and-through connection, which .is

preferably used with the construction of bowl shown. Fig. 6 is a Vertical longitudinal midsection of a wash-out closet. Figs. 7 and 8 are vertical longitudinal mid-sections of two different constructions of shortrhopperclosets, or closets and traps' combined. Fig. 9 is a vertical longitudinal section of a shorthopper closet, showing the bowl and trap in two separate pieces of earthenware.

Referring to the drawings, A designates the bowl of the closet, and B designates the trap by means of which the flushing-pipe is attached to the bowl, and c is the usual standard air-pipe connection for joining the airpipe leading to a Vacuum-tank with the confined air-space d.

In Fig. 2 the upper portion of the soil-pipe E is shown in dotted lines. downward without being provided with any trap until it communicates with the sewerpipe in the lower part of the building. V

In order to ventilate the sewer-pipe E and the space 6 in the trap portion B of the closet between the water seal 0 and the outlet 1), it is customary to provide what is known inthe trade as a back-air connection. According to my invention this connection, lettered'F, consists of two coincidently-opposite openings ff, preferably circular, and so arranged relatively to the soil-passage thataclear open space or passage 9 is formed between them. This space need not have an area equal to that of the openings themselves, it being only necessary that the two shall be sufficiently large to admit the free passage of a tie-bar extending axially from one opening to the other. In the constructions shown in Figs. 1 to 8, inelusive, this passage 9 is exterior to the outline of the soil-passage, so that an axial tiebar thus passed through it will not intersect or enter the soil-passage. In the preferred constructions shown in Figs. 1 to 4 and in Fig. 6 the triangular space between thelegs of the trap is utilized as this passage, this space, instead of being left open, as heretofore, being closed on both sides, with the exception of the two opposite openings ff. In the constructions referred to the openings, since they do notv and 3, and terminate in an opening 2', which either directly enters the space 6, as in Figs. 6, 7, and 8, or communicates indirectly therewith through a downwardly-extending passage as shown in Figs. 2 and 4. In this latter construction the partition in, by which the downward passage j is constituted, has the effect of continuing the siphon action of the soil-passage down below the level of the opening 2 and to the level of the outlet-opening b, as in the construction shown in mypatent, No. 372,199, dated October 25, 1887.

In the two closets shown in Figs. 7 and 8 there is but one trap, the construction being such that no triangular space between the legs of the trap is formed for the passage g. In Fig. 8 such a triangular space is formed between the bowl and the crown or upper swell of the soil-passage beyond the trap by the addition of an exterior partition Z. The exterior side passages h h are here very short, because of the close proximity of the openings f f to the opening 2'.

In the construction shown in Fig. 7 the passage g is built onto the rear of the closet, pro- This pipe leads j ectin g slightly beyond the outline of the soilpassage, and the side passages h hare necessarily of considerable length. A hood k prevents the entrance of water into the openmg L.

In the construction shown in Fig. 9, where the bowl and trap are made of two separate pieces of earthenware fastened together, as is common, the communicating-passage g is an ra nged beneath the ascending and descending limbs of the trap, being inclosed by a partition l applied beneath, and the openings ff being formed in the opposite sides and communicatin g with the opening c, which is at the crown or upward swell of the soil-passage, by passages h, extending vertically. The partitition k isapplied as in Fig. 2.

In the case of traps of the constructions shown in Figs. 6, 7, 8, and 9 the openings f f might be formed directly in the upper part of the space 6; but this would involve the disadvantage of the connecting tie-bar being in the path of the outflowing stream of water and where it might become foul by contact with excreta. The large openings f f might also be entered to some extent by the outflowing water, whereas in the preferred construction the small openings 11 can be arranged so far from the course of this stream that they are not entered thereby.

Fig. 5 shows the preferred construction of metallic through and through connections employed with my invention. There are two heads or caps m and m, the latter being a blind cap, while the former is tubular and formed with a screw-threaded neck, on which screws the coupling thimble or union n, by which the flanged end of a spud 19 is drawn against this neck. The back air-pipe is soldered to the opposite end of the spud 19. From the inner side of the annular cap m projects a forked stem (1, the two forks of which unite in the center in a screw-threaded rod, onto which screws a boss r, projecting from the blind cap m, so that as the latter is screwed up the two caps m and m are drawn forcibly together against the exterior faces around the openings f fin the porcelain. The caps m and m are faced with packing-washers of rubber.

The metal through andthrough connections just described are well known to the trade as those used with the Standard connection hereinbefore referred to. These c011- nections are reversible, so that the back airpipe may be joined to either side of the bowl. The use of this through-and-through connection is not absolutely essential to my invention, since it might be in part availed of by the employment of other connectionswhich do not require that two openings ff be provided in coincidence with each other. As an example of such other connections that may be used, I would refer to the constructions .shown in Figs. 10 and 11, where the opening f on one side of the trap portion B of the closet is omitted, the remaining opening being adapted tobe engaged by a connection applied to one side only. Several such conn ections are already known in the art. In Fig. 11 I have illustrated one such connection that may be used, consisting of a screw-threaded hooked rod t, engaging the inner side of the opening and drawn up by a nut t, screwing on it againsta shoulder formed on the spud 13.

My invention may be modified in other respects than those shown in the accompanying drawings, as will be obvious to mechanics versed in the construction of sanitary earthenware.

I claim as my invention the following defined novel features and combinations, substantially as hereinbefore specified, viz:

1. An earthenware trap formed with coincidently-opposite openingsin its sides which enter a space between the several legs or bends of the trap and within the exterior outlines of the trap, whereby on the insertion of a through-andrthrough connection the latter does not enter the soil-passage, and said trap having a communicating-passage extending from said space to the space between the water seal of the trap and the outlet thereof to the soil-pipe.

2. An earthenware water-closet bowl having its outlet or soil-passage curved upwardly to form a trap, and thence downwardly, and terminating in an outlet for connection with the sewer, and formed with an opening in the side of its trap, portion arranged to enter a space between the several legs or bends of the soil-passage and within the exterior out line of the trap portion, whereby on the insertion of a through-and-through connection the latter does not enter the soil-passage, and

a communicating -passage extending from said space to the space between the water seal and the outlet of the soil-pipe.

3. An earthenware water-closet bowl havin g its outlet or soil-passage curved upwardly to form a trap, and thence downwardly, constituting thereby a space between and bounded by the several legs of the soil-passage, having no direct communication "with the soil-passage, and formed with coincidentlyopposite openings in the sides of its trap portion communicating with said space, and a passage extending from said space and opening into the-space between the water seal and the outlet to the soil-pipe.

4,. An earthenware water-closet bowl havingits outlet or soil-passage curved upwardly to form a trap, and thence downwardly, and terminating in an outlet for connection with the sewer, the descending leg formed with a partition constituting the soil-passage on one side and the vent-passage on the other, the trap portion formed with coincidently-opposite openings in its sides, and with a coinmunicating-passage extending thence and opening into said vent-passage.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
